Abstract

L'invention concerne un système et un procédé servant au tamponnage de plusieurs divisions d'un signal avant transmission. Le tamponnage (800) est configuré pour prévenir la propagation d'erreurs lors du décodage du signal transmis. Un ensemble de niveaux de codage à un taux de transmission donné est sélectionné dans une table de seuil comportant plusieurs niveaux de codage. Chaque ensemble de niveaux de codage comprend plusieurs gammes configurées pour sélectionner les bits codants. Chaque division du signal est codée au moyen de l'ensemble de niveaux de codage. Dans un mode de réalisation, on utilise le système et le procédé de l'invention pour la transmission de signaux vidéo via une voie de communication présentant un risque de pertes.
